FORTUNE's annual ranking of America's leading businesswomen

Sheís the first woman to lead North America for the worldís largest consumer-products company, controlling a whopping 41% of the companyís revenue, or $33.8 billion.
Considered a CEO contender, she managed to give her top line a boost in a tough environment in part by encouraging customers to try new P&G products.

The list is compiled by FORTUNE editors, who consider four criteria: the size and importance of the womanís business in the global economy, the health and direction of the
business, the arc of the womanís career (resume and runway ahead), and societal and cultural influence.
